Eight patients with single ventricle were studied echocardiographically. In six, the ventricular septum was not detectable; in two, a septal-like bulboventricular ridge was identified. Two atrioventricular (A-V) valves were found in all patients; in six, both valves were identified simultaneously with the transducer held stationary along the left sternal edge. Dextro-transposition of the great arteries was noted in three patients. The echocardiogram of one of four patients with levotransposition of the great arteries was consistent with later proved left A-V valve stenosis associated with Ebstein's malformation. Mitral-semilunar valve continuity was presented in five cases. Echocardiographically, the absence of the ventricular septum in a patient with two A-V valves make a diagnosis of single ventricle likely. The presence of ventricular septal-like echoes does not exclude the diagnosis of single ventricle since the right ventricular infundibulum may remain as a small outlet chamber separated from the left ventricle by an eccentric bulboventricular ridge.
对8名单心室患者进行了超声心动图研究。其中6例未检测到室间隔；2例发现有类似间隔的球室嵴。所有患者均发现有两个房室（A-V）瓣；6例中，当换能器沿左胸骨缘固定时，可同时识别两个瓣膜。3例患者发现大动脉右旋位。4例大动脉左旋位患者中的1例超声心动图表现与后来证实的左房室瓣狭窄合并埃布斯坦畸形一致。5例出现二尖瓣-半月瓣连续性。超声心动图显示，有两个房室瓣的患者若没有室间隔，则很可能诊断为单心室。存在类似室间隔的回声并不能排除单心室的诊断，因为右心室漏斗部可能作为一个小的流出腔保留下来，由偏心的球室嵴与左心室分隔开。
